Spa mode is set to standard/ready. See 3 images below with the multimeter readings. One testing both connections, the other two testing one connection plus the heating pipe. The one with both connections measured zero. Thank you!

Hi all, new to the forum and thanks in advance. I have a 2015 Vita Spa Model MONYG, Balboa MXBP501X PN 56549-01 pack. When I increase the goal spa temp above the current temp, the light flashes for calibration, then the low jet setting turns on, however water is not being warmed and the spa temp never rises. Only when I turn the Jets on High will the temp rise 1 degree in a half hour. There are no error messages, and everything else seems to work properly. The circuit board (from the front seems okay, pic attached). I have not recently filled the tub, there are no air locks, the filters are clean and water chemistry is perfect. Issue seems to have started out of the blue. Everything appears 100% normal except that water is not warming. Note I have never seen ANY error messages displayed over the lift of the spa. Please help! Thank you!
